Good day, guys!
I have a question. There is a combined network mikrotik. Between the routers the VPN channel over the EOIP. EOIP in bridge with LAN.
I need to have access to the terminal server via the second router. Recall what needs to be done in routers?
I think, that this is what you are looking for:

Why do I ROMON??? I need the external address of the second router to connect to a terminal server behind the first router
Then I misunderstood what you are trying to achieve.
Then you simply need to create port forwarding NAT rules:

More precisely I need. Using the second router to access the terminal server, which is located behind another router. I recall the routers united VPN tunnel.

You have been given the receipe:
- make port forwarding from external router to the internal one treating it as virtual “terminal server”
- on the internal router make port forwarding to real terminal server
The second router has prescribed this is the rule:
add action=dst-nat chain=dstnat disabled=yes dst-port=624 protocol=tcp src-address-list=white to-addresses=192.168.1.1 to-ports=624
The rule works, but on the first router I do not understand what rule to prescribe to work. Standard port forwarding is not working. What do I have to register on the first router to work?
